This kit contains 4 rubber vibration isolators, which are what essentially transfer the power from the motor to the scrub deck on your CleanFreak dry strip machine. With heavy use they will wear out, which is why we recommend replacing them after extended periods of use. Putting in fresh isolators after many hours of use will make your square scrubber feel like new again.
Other accessories that we off for this machine are the dust control kit, additional 22 lb. weight, and our square scrub, buff & strips pads. (Use w/ the CleanFreak Dry Strip Machine)
